Question

What happens to the value of the expression 70 - 3g as g increases

Answer 1

It decreases

Explanation:

Given the expression: 70-3g

• When g=1, 70-3g=70-3(1)=70-3=67
• When g=2, 70-3g=70-3(2)=70-6=64
• When g=3, 70-3g=70-3(3)=70-9=61
• When g=4, 70-3g=70-3(4)=70-12=58
• When g=5, 70-3g=70-3(5)=70-3=55

From the above, notice that as g increases, the value of the expression decreases.
